GAGE WHEEL ATTACHMENT FOR PLANTERS.

Specification of Letters Patent.

Application filed July 17, 1916. Serial No. 109,711.

To all whom it may concern Be it known that I, JOHN S. MOGABE, a citizenof the United States, residing at Bridgeville, in the county ofAllegheny and State of Pennsylvania, have invented certain new anduseful Improvements in GagelVheel Attachments for Planters; and I dodeclare the following to be a full, clear, and exact description of theinvention such as will enable others skilled in the art to which itappertains to make and use the same.

My invention which relates in general to planters has for its object toprovide simply constructed and inexpensive means for gaging the depth atwhich the planting shoes or disks thereof are permitted to enter theearth. With this general object in view, the invention resides incertain novel features of construction and in unique combinations ofparts to be hereinafter fully described and claimed, the descriptivematter being supplemented by the accompanying drawings which constitutea part of this application and in which:

Figure 1 is an enlarged vertical section of the attachment applied to aportion of a corn planter;

Fig. 2 is a perspective view of the attaching bracket; and

Fig. 3 is a similar view of the bearing sleeve mounted for verticaladjustment in said bracket.

In specifically describing the structure shown in the drawings abovebriefly described, similar characters will be employed to designatecorresponding parts throughout the several views and reference will beherein made to the numerous elements by their respective indices.

Each attachment 1 includes an attaching bracket 2 in the form of avertically disposed cast metal tube having at its lower end a pair ofoppositely extending attaching ears 3 which are alined transversely ofthe tube and disposed in the planeof one side thereof. The opposite sideof the tubular bracket is formed with an internal longitudinallyextending groove 4 and is preferably increased in thickness as shown at5 to prevent said groove from weakening the device. A set screw 6 isthreaded through a boss 7 on the thickened portion a of the bracket andis adapted to secure place a vertically disposed bearing sleeve 8 whichis received slidably in the tubular bracket 2.

The sleeve 8 is of greater length than the bracket and is provided onone side with an external longitudinally extending row of teeth 10 onits outer side, said teeth being received in the groove 4 and beingadapted for cooperation with the set screw 6. It will thus be evidentthat by loosening the screw 6 the bearing sleeve 8 may be adjustedvertically to any desired point and then secured in place by againtightening said screw.

A vertical shaft 11 is received rotatably in the bearing sleeve 8 and isprovided near its lower end with a cup-shaped collar 12 in which thelower end of said sleeve is received. A cap 13 is disposed on the upperend of the shaft 11 over the bearing sleeve 8 and is secured in place bya pin 14:. The lower end of the shaft 11 is forked at 15 and is curvedrearwardly, a gage wheel 16 being rotatably mounted between thefurcations of said fork, and is adapted to travel on the surface of theearth.

In use the device 1 is secured to one end of the hopper frame F so thatthe wheel 16 is spaced outwardly from the shoe S or other earth-workingdevice of the planter being equipped with the improved features. Byloosening the set screw 6, the bearing sleeve 8 is now adjustedvertically to the necessary extent to permit the wheel 16 to penetratethe earth to the required amount by the shoe S or other earth-workingdevice after which said screw is tightened. It is of course understoodthat the planter is to be equipped with a pair of the shoes S or otherearth-working devices, each being secured to the frame as above setforth.

I claim:

A device of the class described comprising a tubular bracket havingattaching ears thereon, a longitudinal rib on the outer face of saidbracket, a longitudinal groove in said rib opening into said tubularbracket, a threaded aperture in said rib to receive a set screw, atubular sleeve having a toothed rib thereon, said sleeve adapted to bereceived in said bracket, the toothed rib being received in said grooveand being held in adjusted position by a set screw, a gage Patented June5, 1917.
